HANGING-MACHINE.

SPECIFICATION forming part of Letters Patent N o. 377,999, datedFebruary 14, 1888. Application Hled November 7, 1887. Serial No.254.559. (No model.)

1 clare the following to be a full, clear, and exact a plan.

description of the invention, such as Will enable others skilled in theart to which it per-l tains to make and use the same.

Our invention relates to improvements in Hanging machines for Hangingthe cheekpieces for metal tackle-blocks; audit consists in cert-aiufeatures of construction and in combination of parts hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is Fig. 2 is a section on line a;x of Fig. 1. Fig. 3 is a section on line y y of Fig. 1. Figs. 4 and 5are enlarged sectional views of the central portion'of the machine, theformer showing the dies closed for Hanging and the latter showing thedies open for removing the blank. Fig. 6 is an enlarged plan of theguides for setting the blank. Fig. 74 is an eularged plan of thesectional former in position distended for Hanging.

A represents a supporting-frame provided with suitable boxes, infwhich:respectively are j ournaled the driving-shaft B and the parallel'shafts C, the latter being intergeared with the driving-shaft bymiter-gears b' and c iu position at right angles to the driving-shaft@On the driving-shaft are mounted cam B and disk B2, the former beingshown in dotted lines, Fig. 3. Disk B2 has a cam-groove, b2, on the oneside thereof. Ou each shaft C are mounted side by side cams C and c, theformer being shown at the left hand and the latter at the right hand inFig.l2. The cam B' operates the lever D, which in turn operates theupper plunger, D', the lever. being fulcrumed at D2, a head, D3, of thelever operating ina mortise of the plunger. (See Fig. 3.) To'the lowerend of the plunger D is attached the primary Hanging-die d. This die isusually oval in plan, and in general terms might be. described asinverted-cup-shaped, the central portion of the under surface or facethereof being Hat, with a .depending rim, d. Aconicabended punch,

ably, to enlarge a smallhole,lj, previously made in the blank J.

The lever E is fulcruuxed at E to frame A, or

plunger is mounted a head or cross-piece, H,

which, when elevated by the plunger F, forms the central member of aformer, over which the blank is Hanged by means of the die d onV 'thedownstroke of thelatter. `The other members, H, of 'the former rest andreciprocate ou the plate A', being held in place by undercut guides A2,that fit the beveled edges of sections d2, depends from the died inposition, prefer- H. These sections are chambered o'r recessed ontheirinner sides at H2, to allow the sections H to come together overthe plunger F and head H when the two latter are depressed. (See Fig.5.) The sections H arev connected by rods Gswith yokes G', in whichyokes operate, respectively, cams c for intermittently reciprocatingsections H.

It will be seen in Fig. 2 that a cam, c, has a-single toe ofmoderatewidth at the base for engaging the respective sides ofthe yoke,from which it follows that the movements of sections H in eitherdirection are quickly made, and that the sections remain stationary sometime at either end of their throw.

.The sections H are undercut along the outer sides thereof, leavingshoulders or underfaced ledges h, under which theedges of the blank areflanged inward by means of dies I. A plate, A3, rests on shoulders a ofthe frame,

and upon this plate the dies I rest and recipunder ledges h there isconsiderableupward pressure against the ledges yanda correspondingdownward pressurebn thefdies. I, and to The dies Ir are curved in planprevent these members from springing apart steel plugs L are secured tosections H in position to support dies I. As these plugs are secured bystuds, they may be adjusted vertically to take up the wear, so as alwaysto tit nicely against the under side of the dies I, such wear beingusually taken up by means of disks of thin metal or paper placed underthe plugs. The dies I attheir outer ends are provided withfriction-rollers I', that are engaged by cams C', by which engagementthe dies I are moved inward. Rods i are fastened to the dies I, theserods being curved substantially as shown in Fig. 2, and having hook endsi', that are engaged by pins C2, projecting laterally from the cams C',and by means of which engagement the dies I are drawn back or outward,the cams on the two shafts C being set to throw simultaneouslyinopposite directions. The middle former-section, H', has a hole, h', forreceiving the punch d2, the hole being somewhat larger in diameter thanthe punch, and the latter having a conical end. A hole, j, havingpreviously been made in the blank, the material of the blank is flangeddown into hole h, thus giving considerable additional thickness for abearing for the pin that supports the sheave ofthe tackle-block. Forinstance, if the blank were a sixteenth of an inch in thickness, thedepending flange j would usually be about an eighth of an inch in depth,thus giving a bearingsurface for the sheavepin of three-sixteenths of aninch. Sections H have semicircular vertical grooves H2, usu ally about aquarter of an inchin depth and large enough in plan to close round theflange j when the sections H are brought together. A guide, K, (shownmore clearly in Fig.` 6,) serves in placing the blank centrally over theformer. Usually a belt-shifter is operated automatically from themachine, and is arranged to stop the machine with the plunger Delevated, and there is a treadle for shifting the belt to start themachine, all of which are old and of ordinary construction, andconsequently are not shown. With the plunger I3 elevated, plunger Fdepressed, sectionsH close together, and dies I drawn out, the blank isplaced in position between the legs of the guide, the blank in suchposition resting on the former-section H.

On starting the machine, iirst the sections H are drawn apart, andimmediately afterward the section H is elevated, thus making a complete55 former. NeXttheplungerD is brought down, the attached die d Hangingdown the edges of the blank over the edges of the former, the dependingflange thus formed extending some little distance below the ledges halong the sides. At the ends, for want of metal in the blank, thedepending flanges only extend down about flush with the under side ofthe section H. Simultaneously with the tlanging just mentioned thepnnehd2 performs its function. Next the dies I are moved inward,engaging so much vof the depending flange already formed as extendsbelow ledge h and Hanging this part ot' the metal under the ledge. Nextthe dies I are moved outward and plunger'D is elevated. Next the sectionH` is depressed, after which the sections H are closed together, thusleaving the different members of the machine at their starting-point,leaving the tinished work free to be removed from the machine.

We have reduced our invention to practice, and have in successfuloperation a large-sized machine capable of tlanging the cheek-pieces fora twenty-inch tackleblock. For each smal-ler size tackle-block sectionsH and H', dies d and I, and guide K are of course changed, and the plateA', being suspended by bolts a, can be raised or lowered to accommodatethe machine to any variation in thickness ot the removable parts. y
